Abstract

A spreading device, consisting of an essentially vertical downpipe (3), on the lower end portion of which a motor-driven spreading plate (16) with a vertical axis of rotation (17) is arranged at the rear eccentric relative to the downpipe axis (31). To reduce or prevent the danger of damage or even destruction of the spreading device when it butts against an obstacle during reverse travel, the downpipe (3) is subdivided in its upper half into two mutually coaxial pipe parts (4, 5) which engage at least slightly in one another and which are thus connected to one another by means of a horizontal joint (6) and by means of a spring element (12). The lower pipe part (5) is resiliently pivotable in the direction of forward travel together with the spreading plate (16), and a signal transmitter (30) for acoustic and/or optical signals, which reacts during the pivoting of the lower pipe part (5), is arranged on one of the two pipe parts (4, 5). <IMAGE>

Description

Die Erfindung betrifft eine Streuvorrichtung für ein auf ein Streufahrzeug aufgesetztes oder aufsetzbares Winterdienst-Streugerät, bestehend aus einem im wesentlichen vertikalen Fallrohr, an dessen unterem Endabschnitt rückseitig ein motorisch angetriebener Streuteller mit einer vertikalen Drehachse exzentrisch zur Fallrohrachse angeordnet ist.The invention relates to a spreader for a winter service spreader placed or attachable to a spreader vehicle, consisting of an essentially vertical downpipe, at the lower end portion of which a motor-driven spreader plate with a vertical axis of rotation is arranged eccentrically to the downpipe axis.

Bei bekannten Vorrichtungen der gattungsgemäßen Art bildet das Fallrohr mit dem exzentrisch daran angeordneten Streuteller eine starre Einheit. Beim Rangieren mit dem Streufahrzeug kommt es häufig vor, daß bei der Rückwärtsfahrt, insbesondere auf unbekanntem Gelände, durch nicht direkt einsehbare Hindernisse die Streuvorrichtung beschädigt oder gar zerstört wird.In known devices of the generic type, the downpipe forms a rigid unit with the scatter plate arranged eccentrically thereon. When maneuvering with the spreading vehicle, it often happens that when driving backwards, especially on unknown terrain, the spreading device is damaged or even destroyed by obstacles that cannot be seen directly.

Der Erfindung liegt deshalb die Aufgabe zu Grunde, ein Winterdienst-Streugerät der eingangs genannten Art zu schaffen, bei dem die Gefahr der Beschädigung oder gar Zerstörung beim ungewollten Anstoßen an ein Hindernis weitgehend vermieden wird.The invention is therefore based on the object to provide a winter service spreader of the type mentioned, in which the risk of damage or even destruction when unintentionally bumping into an obstacle is largely avoided.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß das Fallrohr in seiner oberen Hälfte in zwei zueinander koaxiale, wenigstens geringfügig ineinandergreifende Rohrteile unterteilt ist, die durch ein horizontales Gelenk und durch ein oder mehrere Federelemente so miteinander verbunden sind, daß der untere Rohrteil mit dem Streuteller in Vorwärtsfahrtrichtung federnd verschwenkbar ist und daß an einem der beiden Rohrteile ein beim Verschwenken des unteren Rohrteils ansprechender Signalgeber für akustische und/ oder optische Signale angeordnet ist.This object is achieved according to the invention in that the downpipe is divided in its upper half into two mutually coaxial, at least slightly interlocking pipe parts, which are connected by a horizontal joint and by one or more spring elements so that the lower pipe part with the spreading disc in Forward driving direction is resiliently pivotable and that on one of the two tube parts a responsive when pivoting the lower tube part signal transmitter for acoustic and / or optical signals is arranged.

Von besonderem Vorteil ist die Anordnung des Gelenks im oberen Bereich des Fallrohres deshalb, weil der am weitesten herausragende, besonders empfindliche Streuteller beim Anstoßen an ein Hindernis durch Verschwenken am weitesten ausweichen kann.The arrangement of the joint in the upper region of the downpipe is particularly advantageous because the most outstanding, particularly sensitive spreading disc can deflect the most when it hits an obstacle by pivoting.

Die Ansprüche 2 bis 5 betreffen weitere vorteilhafte konstruktive und funktionelle Ausgestaltungen der Erfindung, die zu einer hohen Funktionssicherheit und günstigen Bauweise beitragen.
Dazu gehört u.a. die Anordnung des Signalgebers gegenüber dem Gelenk am starr verbleibenden oberen Teil des Fallrohres insofern, als schon bei relativ geringer Schwenkbewegung des Streutellers ein sicheres Ansprechen des Signalgebers gewährleistet ist und eine optische und/oder akustische Meldung im Fahrerhaus gegeben werden kann, die den Fahrzeuglenker zu entsprechenden Gegenmaßnahmen veranlaßt.Claims 2 to 5 relate to further advantageous structural and functional configurations of the Invention that contribute to a high level of functional reliability and inexpensive construction.
This includes, among other things, the arrangement of the signal transmitter with respect to the joint on the rigidly remaining upper part of the downpipe, insofar as a reliable response of the signal transmitter is guaranteed even with a relatively small swiveling movement of the spreading plate and an optical and / or acoustic signal in the driver's cab can be given which Vehicle drivers prompted to take appropriate countermeasures.

Bei der in Fig. 1 dargestellten Streuvorrichtung 1, die Teil eines Winterdienst-Streugerätes ist, welches auf der Ladepritsche eines nicht dargestellten Winterdienst-Streufahrzeuges aufgesetzt ist, ist an einem in der Zeichnung nur teilweise dargestellten, horizontal verlaufenden Förderrohr 2, in dem eine nicht dargestellte Förderschnecke als Endlosförderer gelagert ist, ein Fallrohr 3 mit einer im wesentlichen vertikalen Fallrohrachse 31 befestigt. Dieses Fallrohr 3 besteht aus einem vertikalen oberen Rohrteil 4 und einem größtenteils leicht schräg nach hinten verlaufenden unteren Rohrteil 5, die beide in Höhe eines Gelenkes 6 ineinandergreifend miteinander verbunden sind. Der obere Rohrteil 4 ist an seinem unteren Ende mit einem umlaufenden Flanschring 7 versehen, an dem auf der in Fahrtrichtung des Pfeiles 39 vorne liegenden Seite des Fallrohres 3 das Gelenk 6 angeordnet ist. Auf der diametral gegenüberliegenden rückwärtigen Seite des Fallrohres ist der Flanschring 7 mit Stützlaschen 8 versehen.
In analoger Weise ist der obere Endabschnitt des unteren Rohrteiles 5 ebenfalls mit einem Flanschring 9 versehen, der einerseits durch das Gelenk 6 mit dem Flanschring 7 verbunden ist und der auf der gegenüberliegenden hinteren Seite, wo die Stützlaschen 8 angeordnet sind, mit zwei nach unten gerichteten Stützarmen 10, 11 versehen ist, die außerhalb des unteren Rohrteils symmetrisch angeordnet sind.
Zwischen den Stützarmen 10, 11 und den Stützlaschen 8 sind jeweils Gasdruckfedern 12 angeordnet, deren Zylinder 13 jeweils gelenkig am unteren Ende eines Stützarmes befestigt sind und deren Kolbenstangen 14 durch Gelenke 15 mit den Stützlaschen 8 verbunden sind. Dabei ist die Rückstellkraft der beiden Gasdruckfedern 12 so stark, daß diese in der Lage sind, den unteren Rohrteil 5 in bezug auf den oberen Rohrteil 4 in der in Fig. 1 dargestellten Arbeitsposition zu halten, in welcher das untere Ende des oberen Rohrteiles 5 zumindest geringfügig in das obere Ende des unteren Rohrteiles 5 hineinragt und das Streugut somit verlustfrei durch das gesamte Fallrohr 3 geführt bzw. nach unten geleitet wird.In the spreading device 1 shown in Fig. 1, which is part of a winter service spreading device, which is placed on the loading platform of a winter service spreading vehicle, not shown, is on a horizontally extending conveyor pipe 2, only partially shown in the drawing, in which a not shown Screw conveyor is mounted as an endless conveyor, a downpipe 3 with an essentially vertical downpipe axis 31 is attached. This downpipe 3 consists of a vertical upper tube part 4 and a largely slightly obliquely rearward lower tube part 5, both of which are interconnected at the height of a joint 6. The upper pipe part 4 is provided at its lower end with a circumferential flange ring 7, on which the joint 6 is arranged on the side of the down pipe 3 lying in the direction of travel of the arrow 39. On the diametrically opposite rear side of the downpipe, the flange ring 7 is provided with support tabs 8.
In an analogous manner, the upper end section of the lower tubular part 5 is also provided with a flange ring 9, which is connected on the one hand by the joint 6 to the flange ring 7 and on the opposite rear side, where the support straps 8 are arranged, with two downwards Support arms 10, 11 is provided, which are arranged symmetrically outside the lower tubular part.
Between the support arms 10, 11 and the support brackets 8 gas pressure springs 12 are arranged, the cylinders 13 of which are each articulated to the lower end of a support arm and the piston rods 14 are connected by joints 15 to the support brackets 8. Here is the Restoring force of the two gas pressure springs 12 so strong that they are able to hold the lower tube part 5 with respect to the upper tube part 4 in the working position shown in Fig. 1, in which the lower end of the upper tube part 5 at least slightly in that protrudes the upper end of the lower pipe part 5 and the grit is thus guided loss-free through the entire downpipe 3 or directed downwards.

Ein Streuteller 16 ist um eine vertikale Achse 17 drehbar mittels einer Welle 18 in einer Lagervorrichtung 19 drehbar gelagert und durch einen Hydraulikmotor 20 rotierend antreibbar. Die Lagervorrichtung 20 ist mittels eines Tragbügels 21 an einer Montageplatte 22 befestigt, welche ihrerseits am unteren angeschnittenen Endabschnitt 23 des Rohrteiles 5 rückseitig angeschweißt ist. Der untere Endabschnitt 23 des Rohrteiles 5 ist zudem mit einer einstellbaren Rutsche 24 versehen, über welche das durch das Fallrohr 3 fallende Streugut gebündelt punktförmig auf die Oberseite des mit Wurfschaufeln 25 versehenen Streutellers 16 geleitet wird. Unmittelbar über den Wurfschaufeln 25 des Streutellers 16 befindet sich eine umlaufende, konische Abdeckhaube 26, die etwa den gleichen Außendurchmesser aufweist wie der Streuteller 16, die aber mit einem umlaufenden stabilen Schutzring 27 versehen ist, der einen etwa 20 - 30 cm größeren Durchmesser aufweist. Oberhalb des Schutzringes 27 befindet sich ein an der Lagervorrichtung 19 befestigter Schutzbügel 28, der wie der Schutzring 27 die Aufgabe hat, zu verhindern, daß die Schutzhaube 26 oder der Streuteller 16 beim Rückwärtsfahren des Streufahrzeuges ungewollt an irgend welche Hindernisse 29 (Fig. 2) stoßen und beschädigt werden. Um dies sicher zu stellen ragt auch der Schutzbügel 28 nach hinten radial über den Umfang des Streutellers bzw. der Schutzhaube 26 hinaus.A spreading disc 16 is rotatably mounted about a vertical axis 17 by means of a shaft 18 in a bearing device 19 and can be driven in rotation by a hydraulic motor 20. The bearing device 20 is fastened by means of a support bracket 21 to a mounting plate 22, which in turn is welded to the rear at the lower cut end section 23 of the tubular part 5. The lower end section 23 of the tubular part 5 is also provided with an adjustable chute 24, via which the scattering material falling through the downpipe 3 is directed in a point-like manner onto the upper side of the spreading plate 16 provided with throwing vanes 25. Immediately above the throwing blades 25 of the spreading plate 16 is a circumferential, conical cover 26, which has approximately the same outer diameter as the spreading plate 16, but which is provided with a circumferential, stable protective ring 27, which is approximately 20-30 cm has a larger diameter. Above the protective ring 27 there is a protective bracket 28 attached to the bearing device 19, which like the protective ring 27 has the task of preventing the protective hood 26 or the spreading disc 16 from being inadvertently hit by any obstacles 29 when the spreading vehicle is reversing (FIG. 2). bump and get damaged. To ensure this, the protective bracket 28 also protrudes radially beyond the circumference of the spreading plate or the protective hood 26.

Durch das Gelenk 6 ist somit sichergestellt, daß der untere Rohrteil 5 mit dem Streuteller 16 während der Rückwärtsfahrt des Streufahrzeuges beim Anstoßen an ein Hindernis 29 um die Achse des Gelenkes 6 zur Rückseite des Fahrzeuges hin gegen die Haltewirkung der Gasdruckfedern 12 veschwenkt werden kann, wie das in Fig. 2 dargestellt ist. Dabei wird einerseits durch den Schutzring 27 und/oder andererseits durch den Schutzbügel 28 verhindert, daß die Schutzhaube 26 bzw. der Streuteller 16 unmittelbar mit dem Hindernis 29 in Berührung kommt, und es wird auch ein Verbiegen des Fallrohres 3 verhindert.The joint 6 thus ensures that the lower tube part 5 with the spreading plate 16 can be pivoted against the holding action of the gas pressure springs 12 against the holding action of the gas pressure springs 12 during the backward travel of the spreading vehicle when it encounters an obstacle 29 about the axis of the joint 6 to the rear of the vehicle which is shown in Fig. 2. On the one hand, the protective ring 27 and / or on the other hand the protective bracket 28 prevent the protective hood 26 or the spreading disc 16 from coming into direct contact with the obstacle 29, and also prevent the downpipe 3 from bending.

Um jedoch zugleich sicherzustellen, daß der Fahrzeuglenker in dem sich an der Vorderseite des Fahrzeuges befindenden Fahrerhaus auch merkt, daß er beim Rückwärtsfahren mit der Streuvorrichtung gegen ein Hindernis 29 gestoßen ist, ist ein Signalgeber 30, z.B. in Form eines Kontaktschalters vorgesehen, der im Bereich der Stützlaschen 8 und der Stützarme 10, 11 so angeordnet ist, daß bei einem Verschwenken des unteren Rohrteiles 5 relativ zum oberen Rohrteil 4 ein akustisches und/oder optisches Signal im Fahrerhaus erzeugt wird. Die Erzeugung solcher Signale kann mit an sich bekannten Mitteln durchgeführt werden.
Statt der unmittelbar am Flanschring 9 befestigten Stützarme 9, 10 könnte zur Befestigung der unteren Gasfederenden auch ein schellenartiges Stützelement in entsprechender Höhe am Rohrteil 5 mit Stützlagern vorgesehen sein.
Auch ist es möglich, statt der Gasdruckfedern 12 andere Federelemente, z.B. schraubenförmige Druck- oder Zugfedern, zu verwenden.
Durch die Anordnung des Signalgebers 30 in dem angegebenen Bereich wird auch sichergestellt, daß schon bei der geringsten Schwenkbewegung des unteren Rohrteiles mit dem Streuteller 16 relativ zum oberen Rohrteil 4 ein entsprechendes Signal im Fahrerhaus ausgelöst wird, welches den Fahrzeuglenker zum Halten bzw. zum wieder Vorwärtsfahren veranlaßt.However, to ensure at the same time that the vehicle driver in the front of the Vehicle's cab also notices that he has encountered an obstacle 29 when reversing with the spreading device, a signal transmitter 30, for example in the form of a contact switch is provided, which is arranged in the region of the support tabs 8 and the support arms 10, 11 so that at a pivoting of the lower pipe part 5 relative to the upper pipe part 4, an acoustic and / or optical signal is generated in the cab. Such signals can be generated by means known per se.
Instead of the support arms 9, 10 attached directly to the flange ring 9, a clamp-like support element could also be provided at a corresponding height on the tubular part 5 with support bearings for attaching the lower gas spring ends.
It is also possible to use other spring elements, for example helical compression or tension springs, instead of the gas pressure springs 12.
The arrangement of the signal transmitter 30 in the specified area also ensures that a corresponding signal is triggered in the driver's cab relative to the upper tube part 4, even with the slightest pivoting movement of the lower tube part 16, which causes the vehicle driver to stop or to drive forward again prompted.

In den Fig. 1 und 2 ist am oberen Rohrteil 4 ein mit einer ebenfalls horizontalen Gelenkachse 40 versehenes Schwenklager 41 erkennbar, durch welches der obere Rohrteil 4 und somit das gesamte Fallrohr 3 um etwa 180° nach hinten oben in eine Ruheposition geschwenkt werden kann, die bei Leerfahrten über größere Strecken zu bevorzugen ist. Es ist wichtig, daß dieses Verlagern des Fallrohres 3 in seine Ruheposition durch das Gelenk 6 nicht beeinträchtigt wird und daß die von diesem Schwenklager 41 bestimmte Arbeitsposition des Fallrohres 3 bzw. des oberen Rohrteiles 4 erhalten bleibt.1 and 2 is on the upper tube part 4 with A swivel bearing 41, which is also provided with a horizontal joint axis 40, can be pivoted through which the upper pipe part 4 and thus the entire down pipe 3 can be swiveled upward by approximately 180 ° into a rest position, which is preferable for long journeys when empty. It is important that this shifting of the down pipe 3 into its rest position is not impaired by the joint 6 and that the working position of the down pipe 3 or of the upper pipe part 4 determined by this pivot bearing 41 is retained.
